论文摘要
以银河系形成的白矮人是由与太阳相同或更高的质量（即G-Stars）的恒星的残留物形成的。我们知道生活可以在G-Star周围存在。当其明星从主序中过渡并依次进入次级巨人，红色巨人，行星星云和白矮人阶段时，居住在G-Star居住区域内的任何技术先进的文明都将面临严重的危险。实际上，如果文明不采取任何行动，它将面临某些灭绝。被动灭绝的两个替代方法是（a）从母星迁移以殖民另一个星系，或（b）在自己的太阳系中找到可行的解决方案。本文认为，几乎不可能的整个生物人群甚至一小部分的迁移是不可能的，但是无论如何，比在一个人的家庭太阳能系统中更难解决的要难得的要解决，持续生存问题最好解决。这得出的结论是，亚巨头，红色巨人，行星星云和白矮人是SETI观察的最佳候选目标。建议搜索策略。
The preponderance of white dwarfs in the Milky Way were formed from the remnants of stars of the same or somewhat higher mass as the Sun, i.e., from G-stars. We know that life can exist around G-stars. Any technologically advanced civilization residing within the habitable zone of a G-star will face grave peril when its star transitions from the main sequence and successively enters sub-giant, red giant, planetary nebula, and white dwarf stages. In fact, if the civilization takes no action it will face certain extinction. The two alternatives to passive extinction are (a) migrate away from the parent star in order to colonize another star system, or (b) find a viable solution within one's own solar system. It is argued in this paper that migration of an entire biological population or even a small part of a population is virtually impossible, but in any event, far more difficult than remaining in one's home solar system where the problem of continued survival can best be solved. This leads to the conclusion that sub-giants, red giants, planetary nebula, and white dwarfs are the best possible candidate targets for SETI observations. Search strategies are suggested.
